MES Barge Crane for Matson with Rotating Boom and Headblock

Liftech helped design this Mitsui Engineering and Shipbuilding Co., Ltd. barge crane with a rotating boom and headblock for Matson. The headblock hangs from a rotating hoist platform. During normal operations, when the boom rotates, the headblock rotates relative to the boom so that the headblock does not rotate relative to the vessel.

Sydney Low Profile Crane Procurement

Liftech assisted Sydney International Container Terminals Pty Ltd with structural design and review of four post-Panamax ZPMC low profile shuttle boom cranes for their new container terminal across from an airport in Sydney, Australia.

FastNet

Liftech participated with APM Terminals to conceptualize and design FastNet, a crane technology that enables STS gantry cranes to work adjacent, instead of alternate, bays of a large container ship. APMT estimates that FastNet can deliver berth productivity of 450 moves an hour.

POLA Low Profile Crane Conceptual Design

In response to the community’s desire to preserve the marine view, Port of Los Angeles offered to consider low profile cranes for Berths 100–102. Liftech studies indicated that the conventional low profile cranes did not comply with the port’s seismic design standards for the wharves.

VPA Elevating Girder Crane Design

Liftech worked with VIT and ZPMC engineers to develop the elevating girder crane design. The upper works (including the trolley girder, boom, trolley girder support beams, A-frame, apex beam, and stays) may be hoisted to any of five preset elevations to reduce hoisting time to suit ship sizes. Liftech provided full procurement services for the project.

Port Everglades Low Profile Crane Design

Four post-Panamax cranes were designed to meet specific requirements of Port Everglades, including strict aircraft clearance requirements and efficient structures to withstand hurricane winds. The inclined landside leg significantly reduced the weight. An improved adjustable boom hanger system increased reliability and enhanced boom travel performance.

Massport Low Profile Crane Design

Liftech provided the conceptual and final structural design and detail drawings for two post-Panamax low profile container cranes. The inclined landside leg significantly reduced the overall weight, reduced the wheel loads, and allowed for a lightweight boom.

Kaohsiung Post-Panamax Articulated Boom Cranes

Hanjin Heavy Industries provided three cranes for Hanjin Shipping’s new terminal in Kaohsiung. The cranes have an outreach of 52 m (170’-6”) and a rated load of 40.6 t (40 LT). Due to the nearby airport, the height at the terminal is restricted to 70.35 m (230’-10”).

Port of Singapore Machinery-on-Trolley Crane Design

Liftech worked closely with MHI engineers to optimize the crane weight and structural performance of both the main crane structure and the trolley. The resulting structural design meets all of PSA’s stringent deflection requirements. The boom features a trapezoidal monogirder design with a single forestay.

1,700 t Floating Crane Design Review “Left Coast Lifter”

Liftech provided design assistance and review services to American Bridge/Fluor Enterprises (ABF) for procurement of a shear leg derrick. The derrick is used to erect the major components of the San Francisco-Oakland Bay Bridge self-anchored suspension span. The crane with a 100-m boom has 1,700 t capacity at 60 degrees. The crane has two auxiliary hooks with capacities of 100 t and 10 t. The boom is configured to lay down for transport within the USA river system.
